Disclosed are a heating device and a refrigerator. The heating device includes: a cylinder body, in which a heating cavity is defined and configured to place an object to be processed; an electromagnetic generating module, configured to generate an electromagnetic wave signal; a radiating antenna, electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency in the heating cavity according to the electromagnetic wave signal, so as to heat the object to be processed in the heating cavity; and a signal processing and measurement and control circuit, electrically connected with the electromagnetic generating module and disposed outside the cylinder body. In the heating device of the present invention, the signal processing and measurement and control circuit is disposed outside the cylinder body and does not occupy the space of the heating cavity inside the cylinder body, so that the size of the available space inside the heating cavity is greatly increased, thereby increasing the space utilization rate of the heating cavity. At the same time, the heat generated by the signal processing and measurement and control circuit during operation may be prevented from entering the heating cavity and being transferred to the object to be processed, thereby improving the heating uniformity.

A microwave treatment device comprises a heating chamber for accommodating a heating target, a microwave generator, a feeder, a detector, and a controller. The microwave generator generates a microwave having a frequency in a specified frequency band. The feeder radiates the microwave inside the heating chamber. The detector detects a reflected microwave power reflected from the heating chamber. The controller causes the microwave generator to execute a frequency sweeping in the specified frequency band. The controller also controls the microwave generator according to a temporal change in a frequency characteristic of the reflected microwave power. The temporal change in the frequency characteristic of the reflected microwave power is based on the frequency of the microwave, a level of the reflected microwave power, and a time passed from a start of heating. In this aspect, it is possible to accurately recognizes the progress of cooking while heating the object. Accordingly, cooking can be finished appropriately.
